Cephalexin is a type of antibiotic that is used to treat a wide range of bacterial infections. It belongs to a class of antibiotics known as cephalosporins. Cephalexin is commonly used to treat infections of the skin, respiratory tract, bones, and urinary tract. It is also used to treat certain types of ear infections, such as otitis media.
The history of cephalexin dates back to the early 1950s when it was first discovered by scientists at Eli Lilly and Company. The drug was initially developed as a treatment for gonorrhea, but it was found to be effective against a wide range of bacterial infections. It was approved by the US Food and Drug Administration (FDA) in 1971.
Cephalexin is a semisynthetic antibiotic, meaning it is derived from a naturally occurring antibiotic. The active ingredient in cephalexin is cefalexin, which is a cephalosporin antibiotic. It works by inhibiting the growth of bacteria by blocking the production of certain proteins that are essential for bacterial growth.
Cephalexin is available in a variety of forms, including tablets, capsules, and oral suspensions. It is also available as an injectable form. The most common brand names for cephalexin are Keflex, Cefadroxil, and Cefaclor.
Cephalexin is generally considered safe for most people, but it can cause side effects in some people. Common side effects include nausea, vomiting, diarrhea, and abdominal pain. It can also cause an allergic reaction in some people.
Cephalexin is a useful antibiotic that can be used to treat a wide range of bacterial infections. It is important to take the medication as directed by your doctor to ensure the best results and to avoid any potential side effects.
